Step 1

Add blueberries to inner pot of pressure cooker.

Step 2

Pour in honey.

Step 3

Put pressure cooker on low heat (Keep Warm function if using Instant Pot or other electric cooker) until honey melts. If using frozen berries, this part may take a while, but don't worry. It's worth it!

Step 4

Stir occasionally.

Step 5

When melted, turn pressure cooker to high heat (Saute function on Instant Pot) until honey boils. There will be white-pink bubbles all around the blueberries.

Step 6

When it boils, quickly put on the lid of your cooker, checking that the seals and all components are in good shape, including being in the sealing position.

Step 7

If using an electric cooker, hit the Cancel button, then set to high for 2 minutes.

Step 8

If using a stovetop cooker, bring to high pressure and maintain pressure for a cook time of 2 minutes.

Step 9

When cooking time is over, if using an electric cooker, hit the Cancel button to turn off the heat, and unplug.

Step 10

With a stovetop cooker, remove from heat.

Step 11

Let depressurize naturally.

Step 12

When depressurized, remove lid and turn pressure cooker back on to high heat (Saute function on Instant Pot).

Step 13

Let boil until some of the water has evaporated off, and the jam is nice and gelled when dripped off a spoon. Make sure to scrape the bottom frequently to ensure even gelling.

Step 14

Pour jam into clean half-pint jars.

Step 15

Store in the refrigerator.
